Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a bag-taking and flipping device and a tea packaging machine having the device. Background Technology

[0002] In the modern packaging industry, especially in the tea packaging sector, achieving efficient and precise packaging processes is crucial. Bag picking and turning are indispensable steps in tea packaging. Traditional methods rely heavily on manual operation, which is not only inefficient but also costly, making it difficult to meet the demands of large-scale production. While some automated bag picking and turning equipment has emerged with the development of automation technology, these devices generally suffer from complex structures, poor reliability, and inconsistent picking and turning movements. They cannot adequately adapt to the requirements of picking and turning different sized packaging bags, leading to unstable packaging quality and impacting production efficiency and product quality.

[0003] Therefore, developing a device that is simple in structure, reliable in operation, and capable of efficiently and accurately completing bag picking and flipping operations has become an urgent problem to be solved in the tea packaging industry. Summary of the Invention

[0004] The purpose of this utility model is to provide a bag-picking and flipping device and a tea packaging machine having the same, so as to solve the problems of low efficiency, complex structure and poor reliability of existing bag-picking and flipping equipment, realize efficient and accurate bag-picking and flipping operations, and improve the quality and efficiency of tea packaging.

[0005] To achieve the above technical solution, the technical solution of this utility model is as follows: A bag-taking and flipping device, characterized in that it includes:

[0006] A bag-retrieving and flipping bracket, wherein the bag-retrieving and flipping bracket is provided with a movable guide groove;

[0007] The first drive source is rotatably mounted on one side of the bag-taking and flipping bracket to provide driving force;

[0008] A swing arm mechanism, swayably mounted inside the bag-retrieving and flipping bracket, is driven by the first drive source to swing back and forth; and

[0009] The adsorption component is movably disposed on the movable guide slide, and one end is movably disposed on the swing arm mechanism;

[0010] In this device, the first drive source drives the swing arm mechanism to move back and forth, causing the adsorption component to rapidly flip as it moves along the moving guide chute. This bag-retrieving and flipping device organically combines the bag-retrieving and flipping bracket, the first drive source, the swing arm mechanism, and the adsorption component. This unique structural design allows the first drive source to drive the swing arm mechanism, causing the adsorption component to move and rapidly flip within a specific moving guide chute, achieving integrated bag-retrieving and flipping actions. Compared to traditional bag-retrieving and flipping equipment, this structure greatly simplifies the operation process, improves work efficiency, and has a compact overall structure, occupying little space, which is beneficial for the integration and miniaturization of the equipment.

[0011] Furthermore, the movable guide chute includes a vertically arranged lifting chute and a horizontally arranged moving chute, with a turning chute inclined between adjacent lifting and moving chutes; the turning chute is connected to the lifting and moving chute by a rounded transition. The movable guide chute comprises a vertical lifting chute, a horizontal moving chute, and an inclined turning chute, with the turning chute connected to both the lifting and moving chute by a rounded transition. This design allows the adsorption assembly to move more smoothly when switching between different directions of movement, reducing the impact force caused by sudden changes in direction. During lifting, translation, and flipping, the adsorption assembly moves smoothly, improving not only the accuracy of bag retrieval and flipping but also reducing wear and tear on the equipment, thereby extending its service life.

[0012] Furthermore, the first drive source is a servo motor; the servo motor is fixed to one side of the bag-retrieving and flipping bracket by fasteners; a drive gear is detachably installed at the output end of the servo motor. The first drive source is a servo motor, fixed to one side of the bag-retrieving and flipping bracket by fasteners, with a drive gear detachably installed at the output end. The servo motor can precisely control the output angle and speed, providing a stable and adjustable driving force for the swing arm mechanism, allowing the speed and rhythm of the bag-retrieving and flipping action to be precisely adjusted according to actual needs. Simultaneously, the detachable drive gear facilitates the replacement of gears of different specifications to adapt to different working requirements, and the replacement operation is simple and convenient when the gear is worn or malfunctions, reducing maintenance costs.

[0013] Furthermore, the swing arm mechanism includes a first rotating shaft assembly and a second rotating shaft assembly; both the first and second rotating shaft assemblies are disposed inside the bag-retrieving and flipping bracket, with the first rotating shaft assembly located to the upper left of the second rotating shaft assembly; a first lever is detachably mounted on the first rotating shaft assembly; a swing arm is provided on the second rotating shaft assembly; one side of the first lever is movably inserted into the swing arm. The swing arm mechanism consists of a first rotating shaft assembly, a second rotating shaft assembly, a first lever, and a swing arm, with the first rotating shaft assembly located to the upper left of the second rotating shaft assembly, and the first lever movably inserted into the swing arm. This structural design enables the swing arm mechanism to form a stable transmission relationship during movement. The rotation of the first driving source is converted into the swing of the swing arm through the first lever, ensuring that the adsorption assembly can move and flip according to a preset trajectory, thus enhancing the stability and reliability of the entire device operation.

[0014] Furthermore, the first lever includes a drive swing arm; a drive sector gear is fixedly mounted on one side of the drive swing arm; the drive sector gear meshes with a first drive source for transmission; one end of the drive swing arm is provided with a concave U-shaped drive groove. The drive sector gear is fixedly mounted on one side of the drive swing arm of the first lever for transmission with the first drive source, and the other end is provided with a U-shaped drive groove. The meshing method of the drive sector gear and the drive source achieves efficient conversion of the circular motion of the drive source into the swinging motion of the drive swing arm. The U-shaped drive groove, in conjunction with the swing arm, can transmit power more stably, avoiding slippage or tooth disengagement during transmission, further improving the stability and accuracy of the swing arm mechanism's movement, thereby ensuring the precise execution of the adsorption component's bag-picking and flipping actions.

[0015] Furthermore, the swing arm includes a swing base detachably mounted on the second rotating shaft assembly; smooth guide rods are symmetrically inserted on the swing base; and a limiting block is fixed to the other end of each guide rod. The swing base is detachably mounted on the second rotating shaft assembly, and the smooth guide rods and limiting blocks are symmetrically inserted on the swing base. The detachable swing base facilitates the installation, disassembly, and adjustment of the swing arm, improving the ease of assembly and maintenance of the equipment. The symmetrically arranged smooth guide rods provide stable guidance for the swing arm's oscillation, ensuring the straightness of the swing arm during oscillation, while the limiting blocks effectively limit the swing arm's oscillation range, preventing excessive oscillation that could damage the equipment or cause abnormal bag-retrieving and flipping actions.

[0016] Furthermore, the adsorption assembly includes an adsorption movable seat slidably inserted on a guide rod; a flipping shaft is inserted into the adsorption movable seat; the flipping shaft passes through a movable guide groove, and the contact point is equipped with a rolling bearing; a vacuum suction cup assembly is provided at the end of the flipping shaft. The adsorption movable seat of the adsorption assembly is slidably inserted on the guide rod, the flipping shaft passes through the movable guide groove and is equipped with a rolling bearing, and a vacuum suction cup assembly is provided at its end. The rolling bearing significantly reduces the friction between the flipping shaft and the movable guide groove, making the adsorption assembly move and flip more smoothly, reducing energy loss. The vacuum suction cup assembly can firmly adsorb the packaging bag using vacuum suction, ensuring that the packaging bag will not fall off during bag retrieval and flipping, improving the reliability of bag retrieval.

[0017] Furthermore, the vacuum suction cup assembly includes a suction cup base; a suction cup is mounted in a T-shape on the suction cup base. The T-shaped suction cup increases the contact area with the packaging bag, providing greater suction force compared to ordinary suction cups, ensuring the stability of the packaging bag during bag retrieval and flipping. Even under high-speed movement or certain external interference, it effectively prevents the packaging bag from falling off the suction cup, improving the operational reliability of the bag retrieval and flipping device and the packaging quality.

[0021] 2) The bag-retrieving and flipping device of this utility model has a simple structural design, with tight connections and cooperation between various components, resulting in high reliability. It uses a common servo motor as the drive source, and the installation and disassembly of each component are convenient, facilitating maintenance and repair, and reducing the maintenance cost of the equipment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please see the appendix Figures 1 to 2 The illustration shows a bag-retrieving and flipping device, mainly comprising a bag-retrieving and flipping bracket 1, a first drive source 2, a swing arm mechanism 3, and an adsorption assembly 4. The bag-retrieving and flipping bracket 1 is provided with a movable guide groove 11 to guide the movement of the adsorption assembly 4. The first drive source 2 is rotatably mounted on one side of the bag-retrieving and flipping bracket 1, serving as a power source to provide driving force. The swing arm mechanism 3 is swayably mounted inside the bag-retrieving and flipping bracket 1, and the first drive source 2 can drive the swing arm mechanism 3 to swing back and forth. The adsorption assembly 4 is movably mounted on the movable guide groove 11, with one end movably mounted on the swing arm mechanism 3. When the first drive source 2 drives the swing arm mechanism 3 to move back and forth, it can drive the adsorption assembly 4 to move in the movable guide groove 11 and perform rapid flipping, thereby realizing the functions of bag retrieval and flipping.

[0030] Based on the above embodiments, the movable guide chute 11 includes a vertically arranged lifting chute 111 and a horizontally arranged moving chute 112, with a turning chute 113 inclined between adjacent lifting chute 111 and moving chute 112. The turning chute 113 is connected to the lifting chute 111 and moving chute 112 via an arc transition. This design allows the adsorption assembly 4 to smoothly transition between chute directions during movement, ensuring smooth bag retrieval and flipping actions, reducing impact and wear, and improving the stability and service life of the equipment.

[0031] Based on the above embodiments, the first driving source 2 is preferably a servo motor. The servo motor is fixed to one side of the bag-retrieving and flipping bracket 1 by fasteners, making installation convenient and stable. The output end of the servo motor is detachably equipped with a drive gear, which cooperates with the swing arm mechanism 3 to realize power transmission. The detachable drive gear is easy to replace and maintain.

[0032] Based on the above embodiments, the swing arm mechanism 3 includes a first rotating shaft assembly 31 and a second rotating shaft assembly 32. Both the first rotating shaft assembly 31 and the second rotating shaft assembly 32 are disposed inside the bag-retrieving and flipping bracket 1, with the first rotating shaft assembly 31 located to the upper left of the second rotating shaft assembly 32. A first lever 33 is detachably mounted on the first rotating shaft assembly 31, and a swing arm 34 is provided on the second rotating shaft assembly 32. One side of the first lever 33 is movably inserted into the swing arm 34. This structural design enables the swing arm mechanism 3 to achieve stable swinging under the drive of the first driving source 2, providing reliable power transmission for the movement and flipping of the adsorption component 4.

[0033] Based on the above embodiments, the first lever 33 includes a drive swing arm 311, on one side of which a drive sector gear 312 is fixedly mounted. The drive sector gear 312 meshes with the first drive source 2 to transmit power, thereby receiving and converting power. One end of the drive swing arm 311 is provided with a concave U-shaped drive groove. Through the cooperation of the U-shaped drive groove with the swing arm 34, power can be transmitted better, making the swing arm 34 swing more smoothly.

[0034] Based on the above embodiments, the swing arm 34 includes a swing base detachably mounted on the second rotating shaft assembly 32. Smooth guide rods are symmetrically inserted into the swing base, and a limiting block is fixed to one end of each guide rod. The detachable swing base facilitates installation and adjustment, while the guide rods and limiting blocks limit the swing range of the swing arm 34, ensuring the accuracy and stability of its movement.

[0035] Based on the above embodiments, the adsorption assembly 4 includes an adsorption movable seat 41 slidably inserted on the guide rod, a flipping shaft 42 inserted on the adsorption movable seat 41, the flipping shaft 42 passing through the movable guide groove 11, and the contact point is equipped with a rolling bearing to reduce friction and make the movement of the adsorption assembly 4 smoother. A vacuum suction cup assembly 43 is provided at the end of the flipping shaft 42, which realizes the adsorption and gripping of the packaging bag.

[0036] Based on the above embodiments, the vacuum suction cup assembly 43 includes a suction cup base on which a suction cup is mounted in a T-shape. The T-shaped suction cup design increases the contact area between the suction cup and the packaging bag, improves the stability of the suction, and ensures that the packaging bag will not fall off during bag removal and flipping.

[0037] Specifically, during operation, the first drive source 2 (servo motor) starts, and the drive gear drives the drive sector gear 312 to rotate, causing the drive swing arm 311 to swing around the first rotating shaft assembly 31. The swing of the drive swing arm 311 drives the swing rod 34 to swing around the second rotating shaft assembly 32 through the U-shaped drive groove. The swing of the swing rod 34 pushes the adsorption assembly 4 to move in the moving guide slide 11. When the adsorption assembly 4 moves in the lifting groove 111, the packaging bag is lifted; when it transitions from the turning groove 113 to the moving groove 112, the adsorption assembly 4 moves horizontally and flips, thus completing the bag picking and flipping action. The vacuum suction cup assembly 43 uses the vacuum adsorption principle to stably adsorb and grasp the packaging bag during the movement of the adsorption assembly 4, ensuring the stability of the packaging bag during the bag picking and flipping process.

[0038] Based on the above embodiments, such as Figure 3 As shown, a tea packaging machine includes a frame, a bag storage mechanism, and the aforementioned bag-taking and flipping device. The bag-taking and flipping bracket 1 is fixed to the frame, and the bag storage mechanism is located on the frame, above the bag-taking and flipping device. The bag-taking and flipping device is used to store packaging bags, and it retrieves and flips the packaging bags from the bag storage mechanism, thus automating the tea packaging process.

[0039] Based on the above embodiments, the tea packaging machine further includes a tea vibration feeding device for automatically adding tea leaves; a weighing device is located at the output end of the tea vibration feeding device for quantitatively weighing the tea leaves; a material guiding and pushing device is located below the weighing device and can be raised and lowered to receive the weighing device and insert it into the tea bag output from the bag taking and turning device; a sealing device is located below the material guiding and pushing device for final heat sealing of the finished product.
